To aZZao/tom itmay concern K H M Be it known that LLEwIs G. Baynnafa citizen of the United States, residing at Easton, in the county of: Northampton and State of Pennsylvania, have invented a certain; new. andv useful; Improvement in Flow- Controlling Valves for Conduits, ofwhich the following is a specification. c

This invention relates to valves for controlling the flow of air or. other'fiuid through a pipe or-other conduit so that more than as-s certain predetermined amount of fiu'idi canx' not pass through the conduit in a certain period of time, and is particularly adapted to be used inpipe lines for "supplying com- Y pressed air to individual drills or tools so that the operator can not use more than a certain amount of air in a definite period. The object of this invention is to'provide a simple and positively actingvalve of this 31 further object is to provide a valve of this type which will be reversibleand thereportion of the valve seat.

a valve seat 6, port 7 and a rib 8 similar to those of section 1, but has a sleeve portion fore can not be wrongly applied in a pipe line.

With these objects in view, a valve has been devised, a practical embodiment of which is shown in the accompanying drawings in which- Figure 1 shows a longitudinal section through the valve, Fig. 2 shows an elevation of the valve plate and Fig. 3 shows an end elevation of one of the valve seats.

As shown, the complete valve comprises a pair of cylindrical casing sections 1 and 2 the outer ends of which are threaded for the reception of pipes. Across the inner end of section l is a slightly conical or outwardly beveled valve seat 3 through which is a nearly annular port 4:, a diametrical "rib 5 being provided to support the central disk shaped The section 2 has 9 extended to engage the face ofthe section 1 and form an annular chamber of larger diameter than ports 4 and 7, aiiording com munication between these ports. The valve seat 6 has a circular boss 10 fitting into a corresponding depression 11 in the valve seat 3 this boss serving to support the internally projecting arms 12 valve 13 which is held between the two valve seats in a position to close either port lor port 7 but normally out of contact with both.

In operation, the valve 13 will remain in its central posltion as long as the flow of the leading to-a his drill and use the air to blow out smoke or for other purposes he could not usemore than a "certain amount per minute, this amount being determined by the size of the ports and the size andstrength of the spring If the drill operator should allow more than this predetermined amount to pass through the hose the plate valve would be carried over by the current against one of the valve seats and cut oii' the flow entirely. In order to open the valve again the operator would have to close'ofl the end valve or through the leak port 14 would thenv build up pressure on the back of the valve and allow it to return to normal position work. e c r The valve shown in the present construc tion is adapted to close the port in either valve seat equally well so that it will operate no matter in which direction the air passes through it. For this reason it is immaterial whichqway itis connected'in the hose and it an operator to connect it in wrongly.

It isto be understood that the present showing and description discloses only one specified embodiment of my invention and other forms and modifications are included in the spirit and scope of the invention as expressed in the claims.

What I claim is: p 1. A reversible flow controlling valve for a conduit, comprising oppositely beveled valve seats having annular ports therein, positioned across said conduit, a spring plate may be provided in the shape of aleakiport i :"of the.valvecasingandfihe valveare'secured .togethen'by a collar. 15 which has a flange I supposing the of the hose.
